WHEELED SCRAPER.

SPECIFICATIQN forming' part of Letters Patent No. 703,352,vdated June 24, 1902. Application filed November 2, 1901. `Serial No. 80,948. (No model.)

To all whom, t may concern.:

Beit known that I, THOMAS D. RADCLIFFE, residing at Lawrence, in the county of Douglas and State of Kansas, have invented a new 5 and Improved Wheeled Scraper, of which the following is a specification. l

This invention relates to improvements in earth scrapers or scoops, and primarily has for its purpose to provide a wheeled scraper io of a very simple, economical, and compact nature which can be readily manipulated and which will effectively serve for its in tended purposes.

In its generic nature my invention compre- !5 hends an improved construction of parts, in which is included a novel arrangement of pan or draft devices and means for supporting said devices upon a pair of supportingwheels, that the entire weight of the pan-load 2o is vertically supported upon the said wheels, said arrangement of parts also including the relative manner in which the pan is supported on the axle, and the operators or drivers platform is disposed whereby the weight of 25 the load and that of the driver will be substantially balanced upon the wheel-supports and the horses thereby relieved from supporting the weight of such driver. f

My invention also includes a novel coperative arrangement of the wheel-carrying axle,

a looking latch or detent mechanism for maintaining the pan and axle in a relatively fixed position while carrying the load to Vthe dump, and a wheelengaging frame adapted under proper adjustment to interlock with the wheel and cause the pan to tilt or swing upon its pivotal connection, such operation being effected by the rotation of the wheels in either a forward or backward movement under such adjustment of parts.

In its more subordinate features my invention embodies certain details of construction and novel combination of parts, all of which will hereinafter be fully described, and particularly pointed out in the appended claims,

reference being had to the accompanying Figure l is a perspective View of my im-y proved wheeled scraper, the parts being in 5o their load-conveying position. Fig. 2 is a longitudinal section of the same, the parts being in their digging or pan-filling position. Fig. 3 is a side elevation of the same, showing the position of the parts during a dumping operation. Fig. 4 is a detail view of one of 55 the pan-corners. Fig. 5 isaside elevation, on i an enlarged scale, illustrating the connection of the arched axle, the wheel-lock frame, the draft-bar, and tongue-arm with the pan. Fig. 6 is a vertical section on the line 6 (i of Fig. 6to 5. Fig. 7 is a horizontal section of the same on the liner'7 7 of Fig. 5. Fig. 8 is a detail View of the wheel-lock frame detached. Fig. 9 isa similar view ofthe axle-latch frame. Fig. 10 isaJ perspective view'of the arched 65 axle, and Fig. llis a View of the blank from which the pan-body is formed.

Referring to the accompanyingdrawings, in which like charactersindicate like parts in all the figures, l indicates thepan, which has 7o the usual scoop shape and comprises the bottom la, sides lb, andbackend 1. In my conl struction the pan is made up of a single metal blank of substantially the shape shown in Fig. 10, the end c of thebody portion when 75 bent up, as shown best in Fig. 2,formingthe i back end l. The ends when bent up form the sides 1b, which are made fast to the edges of back 1b by angle-irons ld, the curved part c of the back being braced by the inturned 8o corners b of the ends b, as best shown in Fig. 4.

On each side of the pan, near the forward end,is ixedly secured a bracket 2, curved outwere, as at 2n, and in nnewitnsain brackets e5 2 the pan has upwardly-projecting apertured ears 1f, and in the ear 1e and bracket 2 at each side is mounted a stub axle or pintle 3 3, the purpose of which will presently` appear.r

4 designates the arched axle, the ends of 9o which terminate in spindles 4 to receive the supporting or carrier wheels 5 5. i

Upon each vertical member v4." of the axle is ixedly secured a triangular plate or casting 6, the apex 6 of each of which is aper- 95 l tured to receive the pintles 3 3, as shown, said pintles forming the fulcrum-point on which the archedl axle-bar is pivotally connected f with the pan, or, in other words, the point upon which the pan is i pivotally` suspended roo` from the supportingaxle, which point, as will be clearly seen by referringto Fig. 3, is

arms or pan-frame,7 the forward ends of to the rear of the axis of the drive-wheels 5, such correlation of parts being provided to cause the pan to normally gravitate to its lower or digging position, as will presently more fully appear. I

Upon-each side member of the pan and at a point rearward of the brackets 2 isa bracket 7, and on the bracket 7 is pivotally hung the forwardly-extending arms S of lthe axlelatch frame, which has a :l shape in plan view, its cross-bar Sb being .arranged lto extend over the back 1c of the pan, while the ends of its arms S terminate in locking-lugs 8, adapted under 'a proper adjustment of the several parts in a manner presently described to engage with the triangular mem-` bers on' the arched axle and hold the said axle to itsvertical position and the pan lifted from the ground.

The cross-bar 8b is held to seat upon the cheek or handle-grip 9, projected rearwardly `from the pan back, and to ther said bar 8b is xedly joined the lower end of the verticallyextending spring latch-bar 10. l

11 11 designate what I term the tonguewhich bend inwardly and connect with the draft-tongue 12, their rear ends being made tostraddle the pan sides and terminate in vertically-projecting apertured ears 11n 11*L to engage the pintles 3 3, upon which said ears 11 are pivotally supported.

Vhen the pan is held raised to its load-oarrying position, as shownin Fig. l, the tonguearms 11 are disposed in a substantially horizontal plane and are held from dropping below'such plane by reason of engaging stoplugs 1f on th-e front ends of the pan, as shown. The arms 1l, togetherwith the inner end o'f the tongue 12, serve as supports for the operators platform 13, which is ixedly secured to said arms.

At a point justin advance of the front end of the pan the arms 11 each have a-pendent apertured lug 11C, and on said lugs 11C is pivotally hung the end-gate 14 for covering the front end of the pan when filled. The gate l liis so hung as to gravitate to its normal closing position, it being held from swinging too fardown bya handle-rod 15, that engages the platform 13, as shown. l

A U-shaped member 16, which I call the pan-draft frame, has its side arms 16avpivotally hung in the brackets 17 17, projected forwardly from the front ends of the pan, near `the bottom thereof. This frame 1G forms, as it were, a locking means for holding the pan locked in a proper fixed position during filling and when draft is applied, and for such purpose the cross-bar 1Gb of the frame 16 is made to seat (when thrown forward) in the notched draft-stubs 18, flxedly secured to the arms 11 and the operators platform, as shown. l l Y 20 designates a rectangular frame comprising the parallel side bars 2Oa and the crossbar 20. This frame, which under certain The frame 2O is fulcrumed on the -pintles 3 to swing over the tops of the wheels 5, and.

the two members 2O*z are disposed crosswise of each other and have a limited movement in the direction of their length through the side vbars 20, said members being so arranged thatwhen slid outward in one direction an upperwheel-grip lug20disprovidedandwhen slid in an opposite direction to provide a lower grip-lug 20?. Thus two sets of grip-lugs, a lower, 20e, andan upper, 20, disposed on the same radial plane to the fulcrnm-point of the Y frame 20, are provided.

The frame 20, Which,`as will lclearly be noticed by reference to Fig.3, is fulcrumed eccentrically of the wheel-axis, and4 its ymembers 2Od 20e are relatively so arranged that when/the frame 20 is swung `backiwhich movement is limited by reason of the crossbar Obr engaging with the spring-catch) the said members 20d will clear the wheel-rims and allow for the freejtransportation of the machine without interfering with the traction-wheels, the axis of the wheel and the ful- `Crum-points of the frame 2O being, however,

relatively so disposed that by swinging the frame 20 slightly forward its members 2O(l will engage withthe wheel-rims and become interlocked therewith, as will presently be more fully explained. i In its complete form my improved scraper hasa post 25 projected from the draft-tongue,

on whichis mounted a rein-holder26, such device being provided to enable the operator standing on thefront platform to the more conveniently adjust the several parts lof the scraperduring the operation of loading and unloading.

Assuming the parts to be in a normal posi- .tion-that is, the pan. elevated, as shown in Fig. l-,the wheel-lock frame at this time will be thrown back with its members 20d clear of the wheel-rims, the draft or pan frame 11 wilt ing the notched draft-stubs 18, and the axlelatch frame'will be in a locked engagement with `the triangular blocks on' the arched axle, whichat this time will'be disposed in a vertical plane. To prepare to load, the operator throws the handle-bar of end-gate overin the direction indicated by the arrow in the drawings to open up the front end of the pan.. sudden pull forward on the spring'latch member 8 will release the axle and the pan will gravitate to the ground. The operator now places his foot and presses on the axle, and as the scraper is drawn forward its noseor cutting edge enters the ground and cuts under as the ICO ros

IIO

pan fills, the pan during this operation being held from tilting or turning over by the draftframe 16 engaging the stubs 18. When pan is filled, the end-gate is iirst swung back to close over the front end of pan and with its upper grip-lugs 2Oe in position. The frame 2O is then swung forward to lock with the wheels,

as indicated in dotted lines in Fig. 2, which in turning lift up the pan andat the same time rock the axle to a vertical position to bring the triangular blocks to interlock with theaxle-latch frame 8. The appliance is now in position to convey the load, it being understood that after the pan is lifted and the axle and frame 8 are interlocked the frame 2O is again dropped back to free its members 20e from the wheel-rims. To dump the load, the draft-frame 16 is thrown back on the ax-le in the direction indicated in dotted lines in Fig. 1. The axle-lock frame 8 remains in a looked position during this operation. The frame 2O is now again swung forward to cause its lugs 20dto engaget-he rims or treads of the wheels, as shown in Fig. 3, which causes the pan to be swung entirely over, such operation occurring by reason of axle and frame8remaining intact and the draft frame 16 being freed from the lugs 18. During dumping the members 20d remain in contact with the wheeltreads. To right the pan, itis only necessary to back the team a little to rotate the wheels backwardly to return frame 20, and with it the pan, to the normal position.

From the foregoing description, taken in connection with the accompanying drawings, it is thought the advantages of my invention will be readily apparent to those skilled in the art to which it appertains. A single operator can easily manipulate the pan, and as the adjustments for setting the pan to its loading or unloading position can be effected from the operators platform very little time is lost in the minutia of loading and unloading.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a wheeled scraper, the combination with the arched axle and the wheels mounted on the ends thereof; of a pan pivotally hung on the axle eccentrieally to the axis of the wheels, a latch-frame on the pan, adapted to automatically interlock with the axle to hold the pan to its upright position, and means for holding the pan from tilting over when it is set to its digging position and released from a locked engagement with the axle,-for the purposes specified. 2.
